Abstract:We propose a spherical harmonic analysis method to calculate the impact of non-tidal ocean loading in Guangdong and its surrounding areas using high temporal and spatial resolution sea level change data. This method can fully consider the global impact of the ocean and overcome the incompleteness caused by the direct use of Green’s function method for local integral calculation. We find that the impact of non-tidal ocean loading on ground elevation in Guangdong shows obvious regional characteristics, more than 10 mm along the coastline. The effect decreases as the distance from the ocean increases.
